BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a display substrate, a display panel having the display substrate and a display device having the display panel. More particularly, the present invention relates to a display substrate used in a liquid crystal display (“LCD”) device, a display panel having the display substrate and a display device having the display panel.

2. Description of the Related Art

Generally, a liquid crystal display (“LCD”) device includes an LCD panel which displays an image using a light transmissivity of liquid crystal, and a backlight assembly which applies light to the LCD panel.

The LCD panel includes a first substrate, a second substrate facing the first substrate and a liquid crystal layer interposed between the first substrate and the second substrate. The first substrate includes gate lines disposed along a first direction, data lines disposed along a second direction crossing, e.g., substantially perpendicular to, the first direction, thin-film transistors (“TFTs”) electrically connected to the gate lines and the data lines, and pixel electrodes electrically connected to the TFTs. The second substrate includes color filters corresponding to the pixel electrode and a common electrode disposed on a surface of the second substrate. An arrangement of the liquid crystal layer is altered by an electric field formed between the pixel electrode and the common electrode. Thus, light transmissivity through the liquid crystal layer is varied.

Typically, the gate lines extend in the first direction to receive a gate signal from a gate driving part, and the data lines extend in the second direction crossing the first direction to receive a data signal from a data driving part. In addition, the gate driving part is disposed at a first portion of the first substrate along the first direction to be electrically connected to the gate lines, and the data driving part is disposed at a second portion of the first substrate along the second direction to be electrically connected to the data lines. Thus, the LCD panel may have a rectangular shape when viewed from a top plan view perspective.

However, due to a line arrangement between the gate lines and the data lines and the position of the gate driving part and the data driving part, it is difficult to manufacture the LCD panel having various shapes other than the rectangular shape.

DETAILED DESCRIPTION OF THE INVENTION

The present invention is described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the present invention are shown. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art. In the drawings, the sizes and relative sizes of layers and regions may be exaggerated for clarity.

It will be understood that when an element or layer is referred to as being “on,” “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like numerals refer to like elements throughout. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present invention.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein are to be interpreted accordingly.

The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting of the present invention. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

Example embodiments of the invention are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized example embodiments (and intermediate structures) of the present invention. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, example embodiments of the present invention should not be construed as being limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, an implanted region illustrated as a rectangle will, typically, have rounded or curved features and/or a gradient of implant concentration at its edges rather than a binary change from implanted to non-implanted region. Likewise, a buried region formed by implantation may result in some implantation in the region between the buried region and the surface through which the implantation takes place. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of the present invention.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Hereinafter, exemplary embodiments of the present invention will be explained in further detail with reference to the accompanying drawings.
